I got a chance to peep the OLPC product at Drupal Camp last weekend in Berkeley. Now mine is on its way.
This project may or may not work, but it's the strongest concerted effort to date by socially conscious technologists to directly alter the course of human events. I think it sets an important precedent.
Plus, based on my brief test drive, these are awesome little machines. I'm looking forward to playing with mine.
Update: extended through the end of the year if you want one (thanks for the tip, Andrew!)
